Our Services

NAPC are the UK’s only sector specific Annexe, Mobile Home, and Garden Room planning and development consultancy, that offers a dedicated Partnership scheme. Our dedicated Partner Scheme is designed exclusively for select partner organisations, with the aim to improve their service levels and grow their respective businesses.

  • Understanding the context of a site is essential for realising its full potential. And that can make a substantial difference to the project’s profit potential for your business.


Our expert team is on hand to investigate the site and provide the critical information and advice you need.

Our feasibility studies cover:

  1.     Review of LPC policy
  2.     Review of site opportunities and constraints
  3.     Review of planning history
  4.     Design and location advice”

A planning statement is your opportunity to prove the site meets all relevant planning policies. We harness all of our experience to develop and present a keenly focused, clearly argued document packed with pertinent facts and tick-box points. Designed to show the proposal in the best possible light, our planning statement will give your project the best chance of being approved.

With over a decade’s experience of creating and submitting more than 500 annexe planning applications to 250+ local authorities, we have the know-how to help take your project forward from inception all the way to planning approval and beyond.

We can prepare and submit Certificates of Lawfulness for both proposed and existing proposals. That includes even the most potentially contentious of projects. For example, we can prepare a Certificate to cover an existing Class E permitted development garden room, or to ensure a proposed mobile home complies with the definition of a twin unit Caravan (as found within section 13 of the Caravan Sites Act 1968, and as amended in October 2006 (CSA)).

Based on our extensive experience and knowledge of planning case law, we can offer impartial and unbiased advice on whether an appeal will be your best option. If we believe it is, we can then handle all aspects of the process, providing the necessary appeal statements and lodging the appeal in a timely manner on your behalf.

If you receive an enforcement notice on your garden structure, annexe or other type of garden room, it’s vital you act as quickly as possible. NAPC can provide fast, reliable advice on your best next steps. If we believe you have grounds to appeal the enforcement and you choose to follow that path, we’ll have just 28 days to ensure the relevant appeal documents are in the hands of the Planning Inspectorate. So you can trust us to move swiftly and efficiently throughout this critical period.

Here at NAPC we offer expert advice on the Community Infrastructure Levy, and we can act on your client’s behalf to complete all the necessary documentation and apply for any available exemptions. We also offer sound advice on third party requirements – including Ecology, Drainage and Arboriculture – and we’re happy to recommend our excellent third party partner consultants to provide you with further specialist services.
